Hey guys,

Just bought a brand new rig specs:
Intel Q6600 2.4ghz quad core
2 x 8800 Ultra (EVGA)
2 x Corsair PC2-1066 Dominator
ASUS P5N-E SLI Motherboard
Creative Audigy SE
850 Watt NZXT Powersupply. 4 x 12v rail, each at 20A

So heres the problem:
I can boot into vista just fine, but when I try to run a big 3d application the computer will randomly shut down. I have all vista drivers, have tried reseeding all of the components. I am kind of out of options here. We are trying to update the bios now, was just wondering if anyone has heard anything or has any suggestions

Thanks

Hi it can be a heat problem. Do you have adequate ventilation in your case? What are the temperature measurements from your graphics cards and cpu?
